ROOFNGL Application led July 14, 1921. Serial No. 464,568.

To alZZ whom it may concern Be it known that we, JOSEPH F. DONAHUE and MAnioN Gr. STALEY, citizens of the United States, residing at South Bend, in the county of St. Joseph and -State of lndiana, have invented certain new and useful Improvements in Roofing, of which the' fol.

' ceiving the adjacent shingles at a right angle 'to the alignment of the overlapped shingles.

A further object iste provide a roof covering for houses comprising vertically and horizontall 'aligned square shingles, said shingles being provided adjacent vone of their corners with *aligned slots for the reception of the edges of adjacent shingles, therebyl forming a complete roof.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in theV drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure l is a top plan view of a portion of a roof formedfrom interengaged shingles.

Figure 2 is a detail pers ective view of adjacent shingles showing t e .interengage ment thereof.

Referring to the drawings, the numeral l 1 designates 'a portion of a roo formed from' a plurality of rectangular sha d shingles 2, which shingles are .preferab square and made from Cpliable or iexi le material. Shingles 2 a yjacent one of their corners are provided with 'relatively narrow slots t,

which slots are disposed at a rightangle te a line drawn between the cornrs 3 and the corners 3a of the shingles. The slots may be formed by a saw, a U-shaped knife or vby slitting the 'shingle with a knife. When cut or slit with a knife a slot would be formed when the edgesl ofthe shingle are interengaged with each other. When a roof is being covered, the shingles are laid in vertical and horizontal alignment as clearly shown in Figure 2 with their corners 3 down wardlly disposed and their -corners 3a upwardly disposed, and adjacent the lower edge of the roof the roof'may be finished with square shin les V5, whichshingles 5 are not provided with slots 4 for the reason that it gives a better iinish and at the same time the corners a will not be weakened in such a manner that they will bend upwardly. When laying a roof, the shingles 5 vare pllaced in horizontal alignment as shown in igure 1 with their corners '5a downwardly disposed, and their corners 5b upwardly disposed. By so arranging the shingles the other diagonally disposed corners 5c will be in horizontal alignment with each Other, and slightly spaced from each other, thereby allowing the similarly disposed shingles 2 in the vcourse aboveA to receive the diverging edges 5i of the adjacent shingles 5 in the course below, said diverging edges being received in the aligned slots 4: of the shingles 2. `When the edges 5d are disposed in the slots l, it will bel seen that the portions la of the shingles 2 will engage under the sides of the shingles in the course immediately below and will consequently be held in place and at the same time the inner ends 4b of the slots will engage the diverging edges of adjacent shingles 1n the course below at points below the corners 5 of the shingles 5 and 2a of the shingles 2, thereby holding the shingles against downward movement` and maintaining the same in interlocked engagement with each other in such a manner that they are prevented against downward movement and against curling upwardly at their lower ends, Awhich is a reat objection with pliable or Hexible shinges used at the present time.

llt will be seen that one standard form and size of shingle may be used for the entire 'root if so desired, thereby allowing the shin es to be easily and cheaply manufacture, and also thatthe interengaging and interlockingmeans is extremely simile, tlzlereI by allow; gthe roof, to be q formed at a minimum cost. jBy providmg relatlvely narrow lslots or cuts, the adjacent shingles when disposed in the cuts are held in such a manner whereby when a workman walks l their downwardly converging sides disposed` 'in said slots end held against downward -movement by ille inner ends of said slots.

2.. A roof orniedirom shingles having` over the roofing a .sharp bend is not 'formed inthe shingles which are disposed in ille slots and consequently the :material is not.

fractured.

The invention having loeen sei forth what is claimed asnew and nseinl is 1:.- f

1.' A roof formed from a phirality of rec- I tangular shaped shingles having opposite corners in vertical end horizontal alignment; said shingles having their lower ends provided with horizontally disposed aligned narrow slots, the adjacent shingles having corners, said shingles adjagentv one ojrfilieir monroe y ilnres.
